They make two versions - a 49PSI version and a 60PSI version.
Good to know you don't have any fumes problems... are you using an EEC tank and venting via the original EEC plumbing, or venting some other way? Your builds are always sweet - was admiring your custom sump, and also your modified sender. Nice work!

I would think any problems you would have having the high pressure pump pull the fuel out of the tank, you would have with the low pressure pump. It seems to me that it wouldn't be able to keep up with the high pressure pump, but maybe not though.
I have the EEC tank and its all plumbed like factory all the way back to the charcoal cannister. The only difference is there's no vacuum to it. I was going to try to usr the purge solenoid, but wasn't sure it would work without the tank pressure sensor. The charcoal cannister is basically a vent and it keeps the fuel smell away when you park the truck inside. I do have all new hoses for the EEC part of the tank in the cab. But there are no rubber hoses on the actual fuel lines in the cab, that seemed like a bad idea to me, so its all hard line..
I've had set ups where the high pressure pumps pull the fuel out of the tank, and while not optimal, it will work. Just make sure you have a pre-pump filter and its not too restrictive.
